Answer:

56.714°

Step-by-step explanation:

Since we do not have a full angle of this proposed triangle, we must do this by splitting it into two right triangles instead of using the law of sines.

250m*sin(40°) = 250m*0.64278760968 = 160.696902422m

452.4m-160.696902422m=291.703097578m

Use pythagorean theorem:

$\sqrt{250^2 - 160.696902422^2}$

62500-25823.494448025787=36676.505552

$\sqrt{36676.505551974216}$ = 191.511110779m

arctan(291.703097578m/191.511110779m)≈56.714°

Please help and thank you!

The conversion is

$x = r \cos \theta$

$y = r \sin \theta$

$\dfrac y x = \tan \theta$

We're given the fairly unusual

$\theta = -\frac 5 2$

It's fairly unusual because usually an angle is given in degrees or radians, and typically the radians are a fraction times pi. We'll assume radians.

$\dfrac y x = \tan \theta = \tan(-5/2) \approx 0.747$

Ah, there's our .75. The approximate answer is

$y = 0.75 x$

Third choice.

The exact answer is

$y = x \tan( -\frac 5 2)$

also a line through the origin.

What is the answer to this

Maurinko [17]

${x}^{2} - 9x - 36 = 0 \\ (x - 12)(x + 3) = 0 \\ x - 12 = 0 \\ x = 12 \\ x + 3 = 0 \\ x = - 3$

12 x 5= 60

12 x 6 =72

12 x 7 = 84

12 x 8= 96

12 x 9= 108

12 x 10 = 120

12 x 11=132

Identify the inequality that represents the following problem "Two more than three times a number is at least eight" What is the

lesantik [10]

The right answer is Option C.

Step-by-step explanation:

Given word problem is;

Two more than three times a number is at least eight

Let,

n be the number.

Times a number = 3n

Two more means addition;

Two more than three times a number = 3n+2

At least eight means that it can either be 8 or more.

Therefore,

3n+2≥8 is the solution set.

The right answer is Option c.
